【正确答案】　什么时候 　　对这段时光的定义 　　Life is short. I cherish every moment in my life. In my opinion, the best time in the life is childhood. I always recall my memory. I spent my childhood in Kaifeng, which is an old city in middle part of China. I always invited my friends to climb the ancient Wall, picking up a kind of fruit. In spring, we had fun of flying kites, telling stories to each other, playing seek-and-hide. At summer night, we rushed to the food stand, enjoyed the delicious food. How time flies, I have been twenty five years old and experienced some hardship, but when I recall that time, I feel so warm and comfortable.
